Depressed? Check your blood pressure!

The link between depression and cardiovascular health is well-known although the mechanism behind the relationship is not well-understood.

A study by Dutch researchers may just give us an idea of the complexity of that link. For one thing, contrary to the common perception that depression can lead to hypertension, depression, is, in fact, associated with low blood pressure. However, medications against depression – the so-called anti-depressants can increase blood pressure. In particular, tricyclic antidepressants (TCAs) can increase the risk for hypertension.

The study results showed that compared with health controls, MDD patients have significantly lower blood pressure. However, MDD patients on TCA had significant higher blood pressure. The use of SSRIs doesn’t seem to be associated with blood pressure measurements.

So the next question is

Is it the depression that lowers the blood pressure or is it the low blood pressure that causes the depression?

The authors speculate that three things might influence the depression-low blood pressure link.

Use of anti-hypertensive drugs

Common causes of depression and low blood pressure, e.g. fluctuations in metabolites, hormones or neurotransmitters
